Cable management device

ABSTRACT

A cable management device includes a first main body and a second main body. The second main body is connected with the first main body. The second main body is elastically deformable, and selectively in an unwrapped state or a wrapped state. When an elongated strip of the second main body is in the unwrapped state, two ends of the elongated strip are far away from each other. Consequently, a connecting cable can be easily wound around the first main body. In response to an external force, the second main body is elastically deformed to the wrapped state. In the wrapped state, the two ends of the second main body are close to each other, and the connecting cable on the first main body is confined. Consequently, the cable management device can protect the connecting cable, and the cable management device has a compact and small size.

FIELD OF THE INVENTION

The present invention relates to a portable device, and more particularly to a portable cable management device.

BACKGROUND OF THE INVENTION

Nowadays, wearable devices are very popular products. Some wearable devices are wireless wearable devices, but some wearable devices are wired wearable devices. The wired wearable device has a connecting cable. Through the connecting cable, the user can operate the wired wearable device conveniently. In addition, the connecting cable can enhance the flexibility of connecting two individual objects. Take a headphone as an example. The length of the connecting cable of the headphone influences the flexibility of using the headphone. Generally, the longer connecting cable can increase the flexibility of using the headphone. However, if the headphone is not used, it is important to manage the connecting cable in order to be conveniently used in the next time. Consequently, various cable management devices have been disclosed.

For example, a conventional cable management device comprises a box-shaped main body. A winding shaft is disposed within the box-shaped main body for winding a connecting cable thereon. However, this design has some drawbacks. For example, before the box-shaped main body is closed, the user has to accurately wind the connecting cable around the winding shaft to manage the connecting cable. In addition, the limited inner space of the box-shaped main body becomes hindrance from smoothly and conveniently winding the connecting cable.

Furthermore, some cable management devices with lovely shapes have been disclosed. In these cable management devices, a shaft body is used for winding the connecting cable thereon. Since the connecting cable is exposed outside, some drawbacks occur. For example, if the cable management device is placed beside another object, the object is possibly entangled by the connecting cable and thus the connecting cable is pulled by the object. Under this circumstance, the connecting cable and the device connected with the connecting cable are possibly damaged.

Therefore, there is a need of providing an improved cable management device for facilitating storing and releasing a connecting cable while protecting the connecting cable and achieving a portable function.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In this context, the first main body is used as a winding shaft of a cable management device of the present invention. The first main body is a solid body, a hollow body with rigidity or an elastic body with rigidity so as to withstand an external force. The first main body is composed of one or more outer surfaces that are made of identical or different material, or the first main body is an integral part or an assembled component. For facilitating winding a connecting cable, the outer surface of the first main body may be inwardly concaved or threaded. Optionally, the first main body further comprises one or more openings or cavities. The shapes, number, sizes or positions of the openings or cavities are not restricted. The openings or cavities may be used for decoration. Alternatively, an inner space of the first main body is in communication with the outside of the first main body through the one or more openings. The functions of the openings are not restricted to those mentioned above. In addition, an accommodation space within the first main body may be defined by the outer surface of the first main body. The accommodation space can be used to accommodate a part of an object including the connecting cable. In case that the first main body is a solid body, a three-dimensional shape is constructed by the outer surface of the first main body. An example of the three-dimensional shape includes but is not limited to a cylindrical shape, a semi-cylindrical shape, a spherical shape, an ellipsoid shape, a hourglass shape or any other shape suitable for winding the connecting cable thereon.

In this context, a second main body is elastically deformable and selectively switched between at least two states. The second main body is an elastically deformable component that is made of a metallic material, an alloy material, a plastic material or a composite material. Optionally, an outer layer is formed on the elastically deformable component in order to be suitably contacted by the user's hand. The second main body will be illustrated by taking an elongated strip as an example. It is noted that the shape of the second main body is not restricted. Preferably, the second main body has the shape with two recognizable ends. Moreover, by applying an external force to the second main body, the second main body can selectively switched between the two states. When the second main body is switched between the two states, the relative positions between the two ends of the second main body along the longitudinal axis can be adjusted. Preferably but not exclusively, the two ends of the second main body along the longitudinal axis are close to each other or overlapped with each other. Consequently, an interspace or a receiving space is formed between the first main body and the second main body. Since the second main body is switched between the at least two states, the second main body and the first main body can cooperatively achieve the functions of the cable management device.

In this context, a connection element is used for connecting the first main body and the second main body. For example, the connection element comprises an extension structure from the outer surface of the first main body and a complementary structure (e.g., a recess) of the second main body matching the extension structure. Alternatively, the connection element comprises an extension structure of the second main body and a complementary structure (e.g., a recess or an opening) of the first main body matching the extension structure. Alternatively, the connection element is an individual component for connecting the first main body and the second main body by a penetrating means, an adhering means, an attaching means or any other appropriate fixing means. Alternatively, the connection element is integrally formed with the first main body and the second main body by a suitable material and a suitable fabricating process.

FIG. 1 is a schematic perspective view illustrating a cable management device according to an embodiment of the present invention. As shown in FIG. 1, the cable management device 1 comprises a first main body 12 and a second main body 22. The first main body 12 and the second main body 22 are connected with each other. In this embodiment, the first main body 12 is a winding shaft for being wound by a connecting cable thereon. The first main body 12 has an outer surface 121. In this embodiment, the outer surface 121 is a spherical surface.

It is noted that the shape of the first main body is not restricted. FIGS. 2A, 2B and 2C are schematic perspective views illustrating some variant examples of the first main body used in the cable management device according to the embodiment of the present invention. As shown in FIGS. 2A, 2B and 2C, the first main bodies 32, 52 and 72 have different shapes. As shown in FIG. 2A, the first main body 32 has a cylindrical shape. As shown in FIG. 2B, the first main body 52 has an ellipsoid shape. As shown in FIG. 2C, the first main body 72 has a hourglass shape with a wider top region, a wider bottom region and a narrower neck region. Optionally, the first main body further comprises one or more openings or cavities at proper positions. For example, an opening 15 is formed in an outer surface 321 of the first main body 32, two cavities or openings 35 are formed in an outer surface 351 of the first main body 52, and the first main body 72 has no openings or cavities. In an embodiment, the first main body is a solid body. Alternatively, in another embodiment, the first main body has an accommodation space. In case that the first main body has the accommodation space, the accommodation space within the first main body is in communication with the outside of the first main body through the opening. In case that the first main body is the solid body, a part of an object (not shown) can be inserted into the cavity of the first main body. It is noted that the function of the cavity of the first main body is not restricted. Moreover, each of the first main bodies 32, 52 and 72 is made of a rubbery material, a plastic material or any other appropriate polymeric material. More especially, the first main body has elasticity. The first main body is deformable in response to an external force. After the external force is removed, the first main body is restored to its original shape. In other words, the first main body can be made of any appropriate material that is deformed in response to the external force and restored to its original shape after the external force is removed. Consequently, the first main body can be conveniently utilized by the user.

Please refer to FIG. 1 again. In this embodiment, the second main body 22 is an elongated flat strip. The second main body 22 comprises a central region 222 and a peripheral region 224. As shown in FIG. 1, the central region 222 is unwrapped along a longitudinal axis (e.g., the X-axis direction). The peripheral region 224 is located aside by the bilateral sides of the central region 222. Moreover, the two ends of the central region 222 include a first end 223 and a second end 225. It is noted that the areas of the components shown in the drawings are not in scale with the components of the real product. That is, the arrangements of these regions are presented herein for purpose of illustration and description only. Moreover, the second main body 22 is the elongated flat strip in contrast to the first main body 12. In practical applications, the second main body 22 is slightly curved. That is, the central region 222 is the highest or lowest of the curved profile. For example, if the second main body 22 is placed on an X-Y plane, the central region 222 is contacted with the X-Y plane, but the peripheral region 224 is left away from the X-Y plane by a distance. That is, if the peripheral region 224 is contacted with the X-Y plane, the central region 222 is left away from the X-Y plane by a distance. The shape of the second main body 22 is not restricted. For example, in another embodiment, the second main body 22 is substantially a flat plate. In the first embodiment, the second main body 22 is an elastically deformable resilient strip that is made of a metallic material, an alloy material, a plastic material or a composite material. Moreover, the surface of the resilient strip is covered with an appropriate soft material. An example of the soft material includes but is not limited to a rubbery material or a polymeric material. Moreover, when the second main body 22 is applied to the cable management device of the present invention, the second main body 22 is selectively in an unwrapped state or a wrapped state, which will be illustrated later.

As shown in FIG. 1, the first main body 12 and the second main body 22 are connected with each other. In particular, the first main body and the second main body are connected with each other through a connection element. FIGS. 3A, 3B, 3C and 3D are schematic cross-sectional view illustrating some examples of the connection element used in the cable management device according to the embodiment of the present invention. The connection element 2 is used for connecting the first main body 92 and the second main body 62. As shown in FIG. 3A, the connection element 2 is an individual component such as a rivet, a pin or an adhesive element. The connection element 2 are penetrated through or adhered onto a proper position so as to connect the first main body 92 and the second main body 62. For example, as shown in FIG. 1, the proper position is at the first end, at the second end or arranged between the first end and the second end. As shown in FIG. 3B, the connection element 2 includes an extension structure of the first main body 92 and a complementary structure of the second main body 62. For example, the extension structure is formed by covering an article in the first main body 92 in an appropriate fabricating process, and the article is used as the extension structure of the first main body 92. The complementary structure is a recess or a cavity at the proper position of the second main body 62. Consequently, the first main body 92 is fixedly, rotatably or movably connected with the second main body 62 through the connection element 2. As shown in FIG. 3C, the connection element 2 includes an extension structure of the second main body 62 and a complementary structure of the first main body 92. For example, the extension structure is formed by covering an article in a resilience strip, and the article is used as the extension structure of the second main body 62. The complementary structure is a recess or a cavity at the proper position of the first main body 92. Consequently, the first main body 92 is fixedly, rotatably or movably connected with the second main body 62 through the connection element 2. As shown in FIG. 3D, the first main body 92 and the second main body 62 are integrally formed with each through the connection element 2, so that the first main body 92 and the second main body 62 are connected with each other.

Some methods of using the cable management device of the present invention will be illustrated as follows. FIG. 4 is a schematic perspective view illustrating the use of the cable management device for accommodating a part of an object. FIG. 5 is a schematic perspective view illustrating the use of the cable management device for managing a connecting cable of the object. FIG. 6 is a schematic perspective view illustrating the use of the cable management device for wrapping the object in a first implementation example. For example, the object is a headphone, a connector or an adapter. Moreover, any other object having the connecting cable required to be managed can be managed by the cable management device of the present invention. Consequently, the object can be easily stored and carried.

Please refer to FIGS. 4, 5 and 6. One or more openings 45 are formed in the outer surface 421 of the first main body 42. The cable management device of the present invention can be used to manage an object 3 with a connecting cable 32. For example, a first terminal part 30 of the object 3 is inserted into the opening 45 and thus accommodated within the first main body 42. For clarification and brevity, only one first terminal part 30 is shown in the drawings. In some other embodiments, the object 3 comprises one or more first terminal parts 30. According to the requirements of the user, the first terminal parts 30 are not accommodated within the first main body 42, or one, part or all of the first terminal parts 30 are accommodated within the first main body 42.

In case that the second main body 22 is in the unwrapped state, the outer appearance of the second main body 22 is substantially a flat strip, and the first end and the second end of the second main body 22 are far away from each other. Except for the junction between the first main body 42 and the second main body 22, the first end and the second end of the second main body 22 are also far away from the first main body 42. That is, the space between the second main body 22 and the first main body 42 is completely open. Consequently, the user can operate the object and the cable management device of the present invention in the unrestrained space. Moreover, in case that the second main body 22 is in the unwrapped state, the outer surface 421 of the first main body 42 can be used as a winding shaft. Under this circumstance, the connecting cable 32 can be freely wound around the outer surface 421 of the first main body 42. As previously described, some of the conventional cable management devices have a limited space for managing the connecting cable. Since the connecting cable can be wound around the first main body 42 (i.e., the winding shaft) in the unrestrained space when the second main body 22 is in the unwrapped state, the cable management device of the present invention is more advantageous. Under this circumstance, the connecting cable can be managed according to the habit of the user.

Please refer to FIGS. 1, 4 and 6. After the connecting cable is wound around the first main body 42 (i.e., the winding shaft), the user may apply a force to the central region 222 or a proper position of the second main body 22. In response to the external force, the elastically deformable second main body 22 is automatically coiled around the first main body 42 so as to be in a wrapped state. In the wrapped state, the first main body 42 is a wrapped center, and the second main body 22 is gradually wrapped around the first main body 42. Consequently, the space between the first main body 42 and the second main body 22 is an interspace that only accommodates the connecting cable 32. That is, the connecting cable 32 is fixed between the first main body 42 and the second main body 22. Meanwhile, the first end 223 and the second end 225 of the second main body 22 are close to each other. If the length of the second main body 22 is longer than the circumference of the outer surface of the first main body 42, the first end 223 and the second end 225 of the second main body 22 are overlapped and close to the first main body 42, and a second terminal part 34 is exposed outside the second main body 22. In addition, the opening 45 of the first main body 42 is also exposed outside the second main body 22. Consequently, in case that the second main body 22 is in the wrapped state, the connecting cable 32 wound around the first main body 42 is suppressed by the second main body 22 and confined between the first main body 42 and the second main body 22. Under this circumstance, the object 3 and the cable management device are combined as a compact portable device. Consequently, even if the connecting cable 32 wiring around the first main body 42 is in a mess and the volume of the wound connecting cable 32 is either large or small, the second main body 22 wrapped around the first main body 42 can press the connecting cable 32 to be in close contact with the first main body 42. Under this circumstance, the connecting cable 32 will not be entangled with the foreign matter, and object 3 will not be pulled.

FIG. 7A is a schematic perspective view illustrating the use of the cable management device for wrapping the object in a second implementation example. FIG. 7B is a schematic perspective view illustrating the use of the cable management device for wrapping the object in a third implementation example. In comparison with the cable managing approach of FIG. 6, both of the first terminal part 30 and the second terminal part 34 of the object 3 are exposed outside the second main body 22 (see FIG. 7A), or both of the first terminal part 30 and the second terminal part 34 of the object 3 are accommodated within the first main body 42 (see FIG. 7B). Consequently, the user can utilize the cable management device of the present invention to manage the connecting cable of the object in a more flexible manner. Moreover, as shown in FIG. 6, the two ends of the second main body 22 are overlapped on the first main body 42. As shown in FIGS. 7A and 7B, the first end 223 and the second 225 of the second main body 22 in the wrapped state are close to each other (i.e., not overlapped with each other) because the length of the second main body 22 is shorter. However, the connecting cable 32 and the first main body 42 are still wrapped by the second main body 22, and the connecting cable 32 is held in the interspace between the first main body 42 and the second main body 22. In other words, the cable management device of the present invention is capable of managing the connecting cable of the object, so that the object and the cable management device are combined as a compact portable device.

FIG. 8 is a schematic perspective view illustrating the use of the cable management device for wrapping the object in a fourth implementation example. In comparison with FIG. 6, an opening (not shown) is formed in the first main body 52 of FIG. 8. After the connecting cable 32 is wound around the first main body 52, the second main body 22 in the wrapped state will cover the opening Consequently, the opening of the first main body 52 is not exposed outside the second main body 22. In other words, the one or more openings or cavities can be formed at arbitrary positions of the outer surface of the first main body, and the one or more openings or cavities are covered or exposed when the second main body is in the wrapped state.

As mentioned above, the second main body is elastically deformable. If the user intends to use the object, the first end and the second end of the second main body can be both poked away from each other with the user's fingers. Consequently, the second main body is returned to the unwrapped state. Under this circumstance, the object can be easily removed from the cable management device so as to be used. That is, by applying a small force to the second main body, the second main body can be easily switched between the unwrapped state and the wrapped state. Moreover, since the second main body can be switched between these two states, the connecting cable of the object can be wound around the first main body in the unrestrained space. In response to the deformation of the second main body, the object with the connecting cable can be in close contact with the outer surface of the first main body. Consequently, the object and the cable management device are combined as the compact portable device, which can be easily carried.

In addition to the unwrapped state and the wrapped state, the second main body can be operated in an automatic coiled state. In the automatic coiled state, the second main body is automatically coiled in response to the elastic deformation. However, the second main body in the automatic coiled state is not coiled around the first main body but coiled in the direction away from the first main body. Under this circumstance, the space between the coiled second main body and the first main body is also an unrestrained space. When the second main body is in the automatic coiled state, the connecting cable can be wound around the main body through the unrestrained space between the first main body and the second main body. In contrast, if the user intends to use the coiled second main body to wrap the first main body and the wound connecting cable, the user has to apply a force to flatten the coiled second main body. Then, the second main body is wrapped around the first main body (i.e., the wrapped center). That is, the first main body is the wrapped center, and the elastically deformable second main body is wrapped around the first main body so as to be in a wrapped state. Under this circumstance, the connecting cable is confined between the first main body and the second main body. Consequently, the connecting cable is effectively managed by the cable management device of the present invention.
